But if we knew interest rates would stay at 1%, we'd change. Our hurdles reflect our estimate of future opportunity costs.

The model I like to sort of simplify the notion of what goes on in a market for common stocks is the pari-mutuel system at the racetrack. If you stop to think about it, a pari-mutuel system is a market. Everybody goes there and bets and the odds change based on what's bet. That's what happens in the stock market.

It's natural that you'd have more brains going into money management. There are so many huge incomes in money management and investment banking - it's like ants to sugar. There are huge incentives for a man to take up money management as opposed to, say, physics, and it's a lot easier.

Over many decades, our usual practice is that if something we like goes down, we buy more and more. Sometimes something happens, you realize you’re wrong, and you get out. But if you develop correct confidence in your judgment, buy more and take advantage of stock prices.
